Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478580, here are decompositions:

19 + 33478561 = 33478580
103 + 33478477 = 33478580
193 + 33478387 = 33478580
307 + 33478273 = 33478580
349 + 33478231 = 33478580
379 + 33478201 = 33478580
397 + 33478183 = 33478580
571 + 33478009 = 33478580

Showing the first eight; more decompositions exist.
